Race condition in Login Window in Apple Mac OS X 10.5 through 10.5.4, when a blank-password account is enabled, allows attackers to bypass password authentication and login to any account via multiple attempts to login to the blank-password account, followed by selection of an arbitrary account from the user list.

The kernel in Apple Mac OS X 10.5 through 10.5.4 does not properly flush cached credentials during recycling (aka purging) of a vnode, which might allow local users to bypass the intended read or write permissions of a file.

ImageIO in Apple Mac OS X 10.4.11 and 10.5 through 10.5.4 allows context-dependent attackers to cause a denial of service (memory corruption and application crash) or execute arbitrary code via a crafted JPEG image with an embedded ICC profile.

The IMAP server in NoticeWare Email Server NG 4.6.3 and earlier allows remote attackers to cause a denial of service (daemon crash) via multiple long LOGIN commands.

Heap-based buffer overflow in the IMAP service in Qbik WinGate 6.2.2.1137 and earlier allows remote authenticated users to cause a denial of service (resource exhaustion) or possibly execute arbitrary code via a long argument to the LIST command.
